1. TECHNICAL DETAILS
408LD is a versatile micro-controller
based indicator The features offered in
this product are better than any other
Indicator available in similar price range
The instrument is made in 192 (W) x 96
(H) x 70 (D) mm size with standard
cutout of
188 x 92 mm Front is sealed membrane
type to withstand dusty environment
Process value is displayed using four
1 8” seven segment LED displays
The product accepts Pt-100 RTD, J, K, R,
S and T type thermocouples as well as
linear analog input signals like 0-5VDC,
1-5VDC, 4-20mA & 0-20mA The unit
allows configuring input type, zero
value, span value, & displaying
resolution (decimal point information)
Cold junction compensation for the
thermocouple type input & 3-wire
cancellation for the RTD type input is
done using software
Zero & Span settings in case of RTD and
T/C types restrict the usage band, but in
no way restrict the sensing of the input
signal In case the measured value is
outside the range specified by zero and
span settings but within the specified
range for the sensor, the actual value is
displayed but with flashing In case of
linear type input signals, display flashes
for values lower than zero setting and
greater than span setting upto 5% of
span set
Outside the ranges discussed above,
values lower than lower specified ranges
for sensors and
(zero – 5% span) for linear inputs, a
message “OPEN” is displayed while for
values higher than upper specified
ranges for sensors and (span + 5%) for
linear inputs, a message “OVER” is
displayed

5. USER GUIDE
INTRODUCTION
This is a micro-controller based
Universal Indicator designed for multiple
input type
The manual covers all aspects of
operation of the instrument Please read
instructions carefully before altering any
programmed data
POWER SUPPLY
Before switching on the supply power to
the unit, ensure that you have connected
correct input voltage at right terminals
On application of proper power, the unit
will display selected input type for few
seconds followed by displaying actual
value
KEY BOARD
Three keys are provided for operation of
the unit
SET - This key is used as an index key
during configuration mode
Pressing this key in configuration /
calibration mode, saves the presently
displayed parameter value After saving,
the unit moves over to next menu item
automatically
INCR - In configuration / calibration
mode, this key increments the displayed
parameter If kept pressed along with
DECR key at power on, unit enters the
configuration mode If INCR key is
pressed during configuration mode, unit
will enter calibration mode
Cold junction temperature is displayed
for units with t/c type input, if this key
is pressed during run mode
DECR - In configuration / calibration
mode, this key decrements the displayed
parameter If kept pressed along with
INCR key at power on, unit enters the
configuration mode
6. ODES OF OPERATION
CONFIGURATION ODE
This mode is useful for changing basic
configuration of the unit For entering
this mode, switch off the power, press
both INCR & DECR keys simultaneously
and switch on the power to the unit
SET key can be used to move to the
next parameter type, INCR and DECR
can be used to change the selected
parameter value and SET key can be
SET

used to enter/register the new changed
value
Following parameters can be set in this
mode sequentially
INP - Input type
ZERO - Zero setting
SPAN - Span setting
DP - decimal point position
(Display resolution)
INPUT TYPE: Display prompts shown
below appear sequentially to indicate the
type of input that will be selected
rtd - RTD Pt-100
J tC - J type t/c
K tC - K type t/c
t tC - T type t/c
r tC - R type t/c
S tC - S type t/c
1-5v - 1-5 V / 4-20 mA d.c.
0-5v - 0-5 V / 0-20 mA d.c.
Please note:
1) That in case, the zero and span
values are beyond the specification for
the selected input type, the unit will
automatically change the zero and span
value to lower and higher specification
limit
2) That re-calibration is necessary, if the
input type is changed
ZERO & SPAN:
These settings specify the minimum and
maximum range of operation Zero and
span setting for sensors can be
anywhere in their useful range while it
can be set anywhere in between -1999
to 9999 for linear inputs
Zero & Span settings in case of RTD and
T/C types restrict the usage band, but in
no way restrict the sensing of the input
signal In case the measured value is
outside the range specified by zero and
span settings but within the specified
range for the sensor, the actual value is
displayed but with flashing In case of
linear type input signals, display flashes
for values lower than zero setting and
greater than span setting upto 5% of
span set
Outside the ranges discussed above,
values lower than lower specified ranges
for sensors and
(zero – 5% span) for linear inputs, a
message “OPEN” is displayed while for
values higher than upper specified
ranges for sensors and (span + 5%) for
linear inputs, a message “OVER” is
displayed
DECI AL POINT POSITION:
This decides the resolution for RTD & T/C
type sensors and decimal point for linear
inputs On selecting this parameter,
display shows "0000" & the currently set
decimal point glows On pressing INCR
and DECR key, this decimal point is
shifted to right or left respectively, to
indicate the new setting
Input type Display resolution
allowed
RTD, J, K, T 0.1 deg & 1 deg
R, S 1 deg
1-5V, 0-5V full selection
CALIBRATION ODE
Feed simulated close to full scale input
signal to the unit and verify its reading
If the reading is not satisfactory,
calibration may be required
To enter calibration mode, following
procedure has to be followed
For entering this mode, switch off the
power, press both INCR & DECR keys
simultaneously and switch on the power
to the unit The unit will display
“CONF”(configuration mode) message
Now, press the INCR key and message
“CAL” (calibration mode) will be
displayed
Different procedures have to be followed
for different sensors and are explained
below
